That teacher was actually an extraordinarily nice person who I got along with very well lol. He wasn't trying to hurt me, he was trying to help me. The thing is that people who don't stutter have absolutely no idea what goes on behind stuttering and what aggravates it. People who don't care about you will never talk about your stutter. People who care might....and you can tell them that talking about it makes you uncomfortable and they'll understand. They're good at heart and want to help. They're just clueless :)
